Manufactured from steel with a black finish, this plug threads into a 1-1\/4 inch MNPT connection and is rated for a 150 lb pressure class. The countersunk hex socket drive requires a 3\/4 inch socket for installation, allowing torque to be applied in tight spaces where a standard hex head wrench would not fit. It conforms to ASME B16.14 - 1991 dimensional standards, making it a recognized component for use in gas, water, and industrial piping assemblies installed by plumbers, pipefitters, and HVAC technicians.\u003c\/p\u003e\u003cp\u003eThis plug is suited for residential and light commercial applications where black steel pipe systems require a clean, flush-seated pipe end closure. Common install scenarios include capping unused branch outlets on gas distribution manifolds, sealing test ports, or closing off tees during system modification. The countersunk profile sits below the pipe face, reducing the risk of snagging in confined mechanical spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch MNPT thread, 1-1\/4-11-1\/2 thread specification\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class rating\u003c\/li\u003e\n\u003cli\u003eCountersunk hex socket drive accepts a 3\/4 inch socket\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B16.14 - 1991 dimensional standards\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -20 to 350 degrees F\u003c\/li\u003e\n\u003cli\u003eBlack steel construction for compatibility with standard black iron pipe systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-service fitting for 1-1\/4 inch MNPT black steel pipe systems conforming to ASME B16.14 pressure and dimensional requirements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements. Shut off and depressurize the piping system completely before installing or removing any threaded plug. Apply an appropriate thread sealant or pipe tape rated for the service medium before threading the plug into the fitting. Use a 3\/4 inch socket driver to seat the plug; do not overtighten, as this can crack cast fittings or damage threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 1-1\/4-11-1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -20 to 350 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: ASME B16.14 - 1991\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 67767\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952890380594,"sku":"67767","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80d231bd95508cd2dd8486ba6261c14b_4222ded9-dea0-4b74-b184-83a0f49d9125.jpg?v=1791754365","url":"https:\/\/voomisupply.com\/products\/midland-industries-67767-hex-socket-countersunk-plug-1-1-4-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
